If you’re considering a hot water system upgrade in Melbourne, 2026 is the best time to act. Victorian homeowners can currently stack three government rebate programs — the Victorian Energy Upgrades (VEU) scheme, the Solar Homes Hot Water Rebate, and Federal Small-scale Technology Certificates (STCs) — to cover $2,000 to $2,700 or more of the upgrade cost.

Why Melbourne Homeowners Are Upgrading Their Hot Water Systems Right Now
Rising energy bills are pushing more Melbourne households to take action. Your hot water system is one of the largest energy consumers in your home — responsible for 20–30% of your total energy bill. An ageing electric resistance or gas system is likely costing you significantly more than a modern alternative would.
A heat pump hot water system, for example, uses roughly one unit of electricity to produce three units of heat. That is 300% efficiency compared to the 100% you get from a standard electric element. For a typical Melbourne household, switching to a heat pump can reduce annual hot water running costs by $600–$900.
With government rebates bringing the upfront cost down to near zero for many households, the payback period has never been shorter.
Government Rebates for Hot Water Systems in Victoria — 2026 Guide
There are three rebate programs available to Melbourne homeowners right now, and they can all be combined on a single installation.
1. Victorian Energy Upgrades (VEU) Rebate
The VEU program provides an upfront discount on the cost of an eligible heat pump hot water system by creating Victorian Energy Efficiency Certificates (VEECs). This discount is applied directly to your installation price — no waiting, no claiming after the fact.
- Available to all Victorian homeowners and landlords
- No income testing or means testing
- Value: $450 – $675
- Up to 2 claims per property
2. Solar Homes Hot Water Rebate Victoria
The Solar Homes program offers a rebate of up to $1,000 on an eligible heat pump or solar hot water system — and up to $1,400 for select locally manufactured units.
- Available to owner-occupiers only
- Combined household taxable income must be under $210,000 per year
- Existing hot water system must be at least 3 years old
- Property must not have previously received a Solar Homes hot water or battery rebate
- Value: $1,000 – $1,400
⚠️ Critical: You must apply for the Solar Homes rebate and receive your eligibility letter before installation begins. If the system is installed first, the rebate is forfeited. We handle this application on your behalf — just contact us before you do anything else.
3. Federal Small-scale Technology Certificates (STCs)
The Federal Government’s Small-scale Renewable Energy Scheme awards certificates for eligible heat pump and solar hot water installations. These certificates have a monetary value that is passed on to you as an upfront discount.
- Victorian homes (Zone 4) qualify for 14–16 STCs
- Current value: approximately $40 per certificate
- Value to Melbourne homeowners: $560 – $640
- STCs reduce in number every January and phase out entirely by 2030
The longer you wait, the less your STC value. Installing in 2026 gets you more than installing in 2027.

Hot Water System Options for Melbourne Homes
Heat Pump Hot Water Systems (Most Recommended)
A heat pump hot water system is the most popular upgrade choice for Melbourne homeowners in 2026. It works by extracting heat from ambient air and transferring it to your water — making it efficient even on cold Melbourne mornings. Modern units operate reliably down to -10°C, well below anything Melbourne winters typically deliver.
Heat pumps qualify for all three rebate programs, making them the highest-rebate option available.
Best for: Homes replacing an old electric or gas system Running cost saving: Up to 75% compared to standard electric Upfront cost after rebates: $0 in many cases
Solar Hot Water Systems
Solar hot water systems use roof-mounted collectors to heat water directly from the sun. They carry strong long-term running costs and are well suited to Melbourne homes with good north-facing roof space and minimal shading.
Best for: Homes with strong solar access Rebates available: Solar Homes rebate + Federal STCs
Gas Hot Water Replacement — Act Before 2027
From 1 March 2027, end-of-life gas hot water systems in existing Victorian homes must be replaced with an efficient electric alternative. You will no longer be able to replace a gas system like-for-like.
If your gas hot water system is 8 years or older, upgrading now means you avoid the 2027 deadline pressure, access the full current rebate value, and start reducing your running costs immediately.

Frequently Asked Questions — Hot Water Upgrades Melbourne
How much does a hot water system upgrade cost in Melbourne after rebates? After combining VEU, Solar Homes, and STC rebates, many Melbourne homeowners pay very little or nothing upfront for a heat pump hot water system. The exact amount depends on the system chosen and your eligibility for the Solar Homes rebate.
Will a heat pump hot water system work during Melbourne winters? Yes. Modern heat pump systems are rated to operate efficiently down to -10°C. Melbourne’s average winter overnight temperature of 5–7°C is well within that range.
Can landlords claim hot water rebates in Victoria? The VEU discount and Federal STCs are available to landlords and investors — there is no owner-occupier requirement for those programs. The Solar Homes rebate is limited to owner-occupiers.
How long does a hot water system installation take in Melbourne? Most residential installations are completed within 3–4 hours. We remove and dispose of your old system as part of the service.
What is the deadline for the Solar Homes hot water rebate? The Solar Homes program is ongoing but subject to government funding rounds. Apply before installation — once the system is installed, the rebate cannot be claimed retrospectively.
Why should I upgrade before 2027? Federal STC values reduce by one certificate each January, so waiting costs you money. Additionally, from March 2027, Victorian law requires end-of-life gas hot water systems to be replaced with electric alternatives. Upgrading now avoids deadline pressure and captures the highest available rebate.
